Depression is an unfortunately common condition for which people often seek alternative (non-Western) treatments, perhaps because conventional treatments do not consistently provide lasting relief. A pilot study (Allen, Schnyer and Hitt, 1998) suggests that acupuncture, a popular but under-researched alternative treatment derived from Chinese medicine, holds sufficient promise as a treatment for depression to warrant a larger-scale clinical trial. The investigators propose to conduct a larger-scale test of the efficacy of acupuncture in this trial. Because relapse and recurrence of Major Depression are quite common, the investigators also will assess the clinical status of participants for 18 months after treatment concludes. In the first phase of this double-blind randomized clinical trial, 150 men and women meeting criteria for Major Depression will be randomly assigned to a treatment approach or to a waitlist control. All participants will ultimately receive acupuncture designed to address their own particular constellation of depressive symptoms. At the end of this first phase, blind assessments will be used to compare treatment effects from the perspectives of both Western psychiatry and Chinese medicine. After this treatment phase, participants will be assessed several times over the next 18 months. The study is designed to evaluate the efficacy and clinical significance of acupuncture as a treatment for Major Depression, and to examine the convergence of Western-based and Chinese-medicine-based outcome measures. Finally, the study will determine whether changes in energetic pattern mediate changes in Western defined depression severity, and explore whether patient and history variables predict responses to acupuncture treatments.
